摘要 本试验研究择食饲喂对肉鸡生产性能、饲料养分利用率和肉鸡整体粗蛋白、能量转化率的影响。将144羽22日龄艾维因肉鸡随机分成3组,每组4个重复,每重复12羽,每个试验组均设两个食槽,其中试验一组两个食槽中分别放置粉碎玉米和全价配合饲料中的其它组分,试验二组两个食槽中分别放置豆粕和全价配合饲料中的其它组分,对照组也设置两个食槽,均放置全价配合饲料。结果表明:(1)试验组生产性能均显著下降(P<0.01);(2)试验组对日粮干物质、粗蛋白和能量的表观代谢率无影响(P>0.05),对肉鸡整体蛋白沉积率和能量沉积亦无影响(P>0.05);(3)试验一组日粮粗蛋白以及赖氨酸转化为体增重的效率显著高于另两组(P<0.05)。
